when i get the error the user is logging onto a windows 2000 client. The error is reported on the DC and a box comes up and says shutting down in 45 seconds or whatever it is.

I have edited the logon.bat file to read

@ECHO OFF
WKiX32.exe kixtart.kix
and it still fails. I have only 2k clients on the network but all servers are 2003 enterprise servers
